Product catalog summary
Overview: The document provides technical specifications and installation guidelines for longitudinal sight glass fittings, specifically type 334, used for observing and illuminating the interiors of closed containers such as boilers and tanks. These fittings are designed for welding and include a securely screwed sight glass plate.

Specifications:
  • Material: Base frame made of stainless steel (1.4571 or 1.4404), borosilicate glass similar to DIN 7081, and various gasket materials including PTFE, FKM, NBR, C4400, Silicone, EPDM, and Graphite.
  • Temperature: Operates up to 280°C, with higher temperatures available on request.
  • Pressure: Maximum operating pressure is 3 barg.
  • Dimensions: Lengths range from 270 mm to 760 mm, with corresponding weights from 7.4 kg to 18.6 kg.

Installation Notes:
  • After welding the base frame, check for warping of the sealing surface and rework if necessary.
  • Adhere to specified tightening torques for bolting as per operating and maintenance instructions.
  • Ensure the base frame and pressure device comply with AD2000 Leaflet B9.

Product Code Structure: The product code is composed of group type, length, base frame material, glass type, gasket type, and variant. Example: 11-334-550-2-1-4-000.

Operating Conditions: The suitability of sight glass and gaskets depends on temperature and pressure conditions. Borosilicate glass is suitable for temperatures up to 280°C, while different gaskets have varying maximum temperature tolerances.

Optional Accessories: Accessories include nearly dead space-free design, stepped glass, and FEP protective screen/coating for high pH values.
